The MQ7 carbon monoxide sensor is especially designed to be sensitive to carbon monoxide (CO) gas which is emitted by vehicles, factories, etc. Since this gas is considered toxic to humans at certain levels, concentration of CO is used to determine the air pollution in a given area.

7/3/2016· The carbon monoxide sensor we will use is the MQ7 sensor. This is a sensor that is sensitive to effects of CO. Carbon monoxide (CO) is a very dangerous gas which is odorless, colorless, and tasteless, so it cannot be smelt, seen, or tasted.

31/10/2016· This introduces the MQ7 Carbon Monoxide (CO) Gas Sensor module and a simple "Hello World" program to interact with the device. The MQ7 sensor detects carbon monoxide gas concentrations in the air and alerts the user when the levels go past a safe threshold. Carbon Monoxide is a poisonous gas that has no color, odor, or taste.

Introduction. The MQ7 is a simpletouse Carbon Monoxide (CO) sensor suitable for sensing CO concentrations in the air. It can detect COgas concentrations anywhere from 20 to 2000ppm. The sensitivity can be adjusted by the potentiometer.

A carbon monoxide detector for the Arduinobased DIY security system. The carbon monoxide detector is a semiconductor gas sensor tuned to detect carbon monoxide. It is in the same family of devices as the smoke detector sensor, measuring the change in surface conductivity of tin dioxide in the presence of carbon monoxide. This sensor has a high sensitivity and fast response time. The …

I had previously published a project with an MQ sensor and received a lot of critical feedback on it. Today I also expect your feedback, but only of a positive nature: with the MQ7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem.
